docking ports & cargo bays

[NERVAfan]

Can you connect two docking ports of different sizes, like a 1.25m (regular) and a 2.5m (Sr) one?

Also, how do you release something from a cargo bay? It seems to just stay in when I open the bay in space (this is still 0.25 if that matters).

1: No, you cannot. Only same size ports connect

2: you need to put docking ports, decouplers or separators (not advised) between your main craft and payload

You can in the VAB/SPH. It's not really clear if the OP meant in flight or not though.

Know that docking port can decouple thing that themselves don't have a docking port. Meaning you can attach a probes by its engine.

Be careful at the orientation of it control part.

My solution was to open the bay, release the payload, then send a kerbal out to nudge it out of the bay

Or you could just rotate the ship with reaction wheels (gently!), which will give the payload a nudge. If you have RCS you can just use the linear controls to push yourself away from the payload too.

Or just translate away from the payload with RCS

That's what I just said... linear controls = translation

OK, thank you.

I did mean in-flight, sorry.
